Best answer

Correct option  (b) Kinetochore

Explanation :

During late prophase, specialised structules called kinetochores develop on either surface of the centromere, Chromosomal fibres get attached to kinetochore.

Chromomeres are beaded structures on the chromosomes which are found particularly at the prophase-l (particularly at leptotene) of meiosis-I. Chromocentre is developed due to the fusion of centromeric regions of all the chromosomes of a ceIl. Centrosome is found in animal cells (absent in higher plant cells). It is found near the nucleus. Each centrosome is made up of two centrioles and each centriole is e cylindrical structure with a diameter of 1500-1800 A and is made up of nine fibrils.
